装置に係る。[Detailed description of the invention] The present invention is made by dividing the center between the left and right pieces 1 and 2 of the sheet metal material A into upper and lower parts, and forming the upper and lower pieces 3 and 4 into arcuate shapes in opposite directions. The upper and lower pieces 3 and 4 have a screw portion 6a for screwing the bulb cap 5 on the concave curved side of the upper and lower pieces 3 and 4, respectively.
This invention relates to a light bulb holding device in which screws 6b are screwed in the same direction.

従来の電球保持装置は、第１図に示すように絞り加工に

金では径が小さくて強度的な問題から口金接続用中ばね
１０の挿入部切欠１１を第１図に示すように設けること
ができないという欠点があった。In the conventional light bulb holding device, the bottomed cylindrical receiver 7 was manufactured by drawing as shown in Fig. 1, but the manufacturing process was complicated and the cost was high, and the fixing of the receiver 7 was difficult. Pass the stopper 9 through the receiver fixing hole 8 provided in the receiver 7,
Since the stopper 9 was fixed to the outer shell 13 made of molded material by caulking, the insertion part of the inner spring 10 for connecting the cap was not fixed due to the small diameter and strength problem in the E12 type receiver of the 0-ball socket. There was a drawback that the notch 11 could not be provided as shown in FIG.

そのためかかるような０球ソケットにあっては第２図に

同時に固定していたが受金７と中ばね１０との間の絶縁
のために絶縁板１２が必要となって工数並びに部材点数
が増えてコストが高いという欠点があった。Therefore, in such a zero-ball socket, as shown in FIG. The insulating plate 12 is required for insulation, which increases the number of man-hours and the number of parts, resulting in high costs.

尚第１図中、第２図中の１４は端子板である。本考案は
、上述の欠点に鑑みて為したもので、その目的とすると
ころは製造が容易で且つ製造価格が安価である電球保持
装置を提供するにある。In addition, 14 in FIG. 1 and FIG. 2 is a terminal plate. The present invention has been made in view of the above-mentioned drawbacks, and its purpose is to provide a light bulb holding device that is easy to manufacture and inexpensive to manufacture.

以下本考案を一実施例によって説明する。The present invention will be explained below by way of an example.

同一螺進方向の螺子部６ａ、６ｂを夫々螺設して構成し
である。The receiver 7 is a rectangular sheet metal material A shown in Fig. 3, which is divided into two parts at the center into upper and lower pieces 3 and 4, leaving the left and right pieces 1 and 2, and the upper and lower pieces 3 and 4 are divided into two parts as shown in Fig. 4. As shown in the figure, the upper and lower pieces 3 and 4 are curved in an arc shape in opposite directions, and the concave curved surfaces of the upper and lower pieces 3 and 4 are respectively screwed with threaded portions 6a and 6b running in the same direction. .

これらの加工はプレス加工によって行なうもので、螺子

６ａ、６ｂに螺合し、電球りは第５図のように受金７に
保持されることになる。However, you can receive glow starters and other light bulbs.
When the bulb base 5 is screwed into the semi-cylindrical space formed by the upper and lower pieces 3 and 4, the screws on the upper outer periphery of the bulb base 5 are connected to the threaded portions 6a of the upper piece 3, 6 b
The lower outer circumferential screw of the lamp cap 5 is screwed into the threaded portions 6a and 6b of the lower piece 4, and the lamp is held in the receiver 7 as shown in FIG.

尚左、右側片１，２はリード線接続をするための端子部
や、受金７を固定するための固定片として用いるための
ものである。The left and right pieces 1 and 2 are used as terminals for connecting lead wires and as fixing pieces for fixing the receiver 7.

また受金７を装着する成形量の外殻体（図示せず）に電
球口金５の上、下部の残り半部の螺子を螺合するための
螺子部を設けて、受金７と組合せても勿論よい。Further, a threaded portion for screwing together the screws of the remaining half of the upper and lower portions of the bulb cap 5 is provided on the outer shell (not shown) of the molded amount to which the receiver 7 is attached, and the screw portion is assembled with the receiver 7. Of course it's good too.

本考案は、矩形板金材の左、右側片間の中央を上下に２
分割して形成せる、上、下片を相反する方向へ円弧状に
突曲威して受金を構成し、上、下片の凹曲面側に電球口
金螺着用の螺子部を同一螺進方向となるように螺設する
ので、受金を製造するに際しては絞り加工によらずにプ
レス加工を用いることができるので製造が容易となり、
しかも受金が有底形でないため０球ソケットとして用い
る場合にも、中ばねと受金との間に絶縁材を用いる必要
がなく、更にまた左、右側片がそのままリード線接続端
子部を構成することもできて端子板が不要であり、従っ
て製造コストが安価となるという利点を有する。In this invention, the center between the left and right pieces of the rectangular sheet metal material is
The upper and lower pieces, which are formed by dividing, are bent in an arc shape in opposite directions to form a receiver, and the screw portion for attaching the bulb base screw is threaded in the same direction on the concave curved side of the upper and lower pieces. Since the screws are installed in such a way that when manufacturing the receiver, press working can be used instead of drawing process, making manufacturing easier.
Moreover, since the holder is not bottomed, there is no need to use insulating material between the middle spring and the holder even when used as a 0-ball socket, and the left and right pieces form the lead wire connection terminal part as they are. This has the advantage that a terminal board is not required and the manufacturing cost is therefore low.
